I find using flux and a little 15% does wonders on those. I don't like how they are so close to to the body makes me nervous installing them. doing all that work just to find that you burned it up installing it..

i installed a danfoss the other day, i went to set the superheat and was suprised the adjustment was on the side...do u use regular silver solder on those??

LOL.. Yep don't ever try to unscrew the bottom to adjust it you'll be in for a surprise.

As far as short connections on the valves, I'm guess its a cost thing. I just try to burn it in real quick with little 1/2" or so strip of wet rag wrapped around it. With the danfoss valves you heat the pipe mostly then just touch the fitting when the pipe is hot enough.

I get more pissed at the short connections on filter driers then txvs. Got to love the smell of burning paint.

I'd want to see that Danfoss valve in use after that. Not just pipes in a lab.

timebuilder Have you ever brazed in a Danfoss like they show? The Stainless is so thin I would hold the valve by the head while you braze it. You could grab the body shortly after. They show much more heat than is needed IMO.
